This invention relates to new calcium preparations especially adapted for therapeutic use, the

can be supposed that double compounds are formed in the solution.

If desired from a medical view point a suited, easily soluble magnesium salt, as for instance magnesium hypophosphite, magnesium chloride, magnesium acetate or magnesium gluconate may be added to the solutions.

The solutions according to my invention show a good compatibility when injected in usual manner. The especial high calcium concentrations (30 mgs. and more pro cc.) are desired for certain pharmaceutical purposes when high volumes are to be avoided. Furthermore the hypophosphite content of the solutions is valuable for therapeutic purposes.

The solutions may be manufactured by dissolving the compounds in water while warming and filling up the solutions to the desired volume.

1 Claim. (o1. 167-68) Thus, for instance, "solutions with calcium and magnesium contents as stated in the table are obtained when the following amounts of salts are dissolved in water while warming and the solutions are filled up or concentrated respectively to 100 cos.

In a similar manner stable concentrated calcium solutions can be obtained when other proportions of the salts are chosen.

I claim: I As a new therapeutic product a stabilized aqueous solution of calcium lactate containing cal cium hypophosphite as a stabilizing agent said I HANS SCHMIDT.
